HeatMap: Heat map
In metabolomics: Analysis of Metabolomics Data

Description Usage Arguments Author(s) See Also

Produces a heat map of a metabolomics data matrix optionally clustered according to specified methods.

HeatMap(inputdata, colramp = redgreen(75), 
    scale = c("row", "column", "none"), 
    dendrogram = c("column", "row", "both", "none"),
    distmethod = "euclidean", aggmethod = "complete", 
    margins = c(5, 5), key = TRUE, keysize = 1.5, 
    cexRow = 0.5, ColSideColors = NULL, ...)

`inputdata`	A data frame in the input data format. See `metabolomics` for details.
`colramp`	Colours for the image.
`scale`	A character indicating if the values should be scaled metabolite-wise ("`row`") or group-wise ("`column`").
`dendrogram`	A character indicating whether to draw "`none`", "`row`", "`column`" or "`both`" dendrograms.
`distmethod`	The distance measure to be used. This must be one of "`euclidean`", "`maximum`", "`manhattan`", "`canberra`", "`binary`" or "`minkowski`".
`aggmethod`	The agglomeration method to be used. This should be one of "`ward`", "`single`", "`complete`", "`average`", "`mcquitty`", "`median`" or "`centroid`".
`margins`	A numeric vector of length 2 containing the margins for group and metabolite names, respectively.
`key`	A logical indicating whether a colour key must be drawn.
`keysize`	A numeric indicating the size of the key.
`cexRow`	A numeric indicating the size of the metabolite names.
`ColSideColors`	A character vector indicating the colours different groups.
`...`	Arguments to be passed on to other methods.
